I do love me a free gift with purchase at Boots. Something for free is excellent, but also I like to try out different brands, with lure me in with them, of which I don't usually use.
Like this one from Bourjois, it is VERY festive bauble, with a eye shadow in a limited edition shade of gold.
I did not even know they did eye shadow, so got myself a soft pink shade to try, and then a dusky pink shade of lipstick, as it was spend £12 to get the freebie.
These are available in store or online so head over there asap to grab one for your tree!
